APPARATUS FOR GENERATING AGETYLENE GAS.

ernomcmronannln part of Letters Patent No. 614,906, dated. November 29, 1898.

Application filed July 8, 1897a BerlaI'No. 643,844. (No model.)

' the following-is a full and-complete specification, such as will enable those skilled in they art to which it appertains to make and use the same. v I I w v This invention relates to apparatus for generating acetylene gas; and the object thereof is to provide an improved apparatus of this 7 class which issimple in construction and operation and wherein'the calcic carbid which.

is employed for thei'generation of the gas is subdivided or plaoed' in separate receptacles,

one abovethe othtm'jfwherebyl do away with the great inconvenience of an undivided char-goof this material, ,whichcan only with great d-ifliculty be made to yield all the acetylene gas it'is capable of producingwhen not separated in this manner by reason of the fact that when subjected to the action of water acrust of limeforms thereon, which tends to prevent further contact between the water and the calciccarbid. By this arrangement an estimate may also be made with al-.' most absolute accuracy of the volume of'gas produced from the calcic carbid, with the re sult that the gasometer isinvariablycapable of containing all the gas evolved without subjecting, it to undue pressure, and by means of this arrangement it is impossible that there should ever be a production, of gas for which there would notrbe abundant room in the gasoineter may become overcharged.

A further advantage of my construction consists in the automatic devices which -I employ for controlling the flow of the water which is admitted to the calcic carbid. in the generator and in the use of a hydraulic seal for the generator, which feature renders it possible to recharge the generator without-interfering with or suspending the operation of illumination, it being'merely necessaryto close a valve in a pipe which connects the generator with the gasometer in order to recharge the generator.

Af'urther advantage of myimproved apstruction, whereby it is possible for anyone to make and operate the, same or managezit when constructed, and the invention is fully disclosedin the following specification, of which the accompanying drawingsform a part, in which the separate parts of my improvedapparatus aredesignated by the same numeralsof reference in each of the views,

'and in which-- s .Figure 1 is a side view of said-apparatus,

and Fig. 2 a section on the line 2 2 of Fig. 1. In the practice of my invent-ion I provide ,a gasometer which consists-of the usual cylindrical casing or receiver 5, which is filled or partially filled with water in the usual manner and in which is placed a verticallytlie bottom and closed at the top. and which is provided with'the usual guide-rollers 7 and one or more counterbalance-weights 8, which are passed over suitable pulleys 9 and connected with said drum, as shown at 10. All these features of construction, however,

are ,the same as those usually employed and form nopart of this inventionl In the construction of the generator'l employ a cylindrical casing 11, which is provided near its lower end with a transverse partitionplate 12 and inwhich is placeda tubular receptacle 13, which is open at the top. and closed at the bottom and between which and the cylindrical casing 11 is an annular chamber 14. I also employ a supplemental tubular receptacle 15, which is closed at the bottom and open at the top, and placed in the tubular re-' ceptacle 15 is a plurality of small cylindrical boxes'or receptacles, which, as'shown in the wdrawings, are four in number'and which are designated by tho reference-numerals 1t, 17, 18, and 19, and these boxes or receptacles decrease in size from the bottom upwardly, and.

enter or rest upon the top of the box or re- "ceptacle 19, the box or receptacle 17 in the 7" movable pressure-drum 6, which is open at the box or receptaclc'lS is so formed as to receptacle 17, and each of .the boxes or recep- .tacles 16, 17, and 18 is provided near the top thereof with an annular row of 'perforations 3 which is connected a lever 31, :theouter end and said water-receptacle 24 isprovided'with a removable cover and at each side thereof with handles 26, and the casing 22, in which the water;- receptacle 24 is formed, is supported in the position shown in Fig. 2 by side arms or brackets 27, which i are secured thereto and which rest on the bottom of the annular'char'nber 21.- I also provide af-pipe 28, which isbent transversely of the-casing 22.and both ends of which are passed there- 'through into the water-receptacle 24, and one end ofthispipe is passed downwardly through 'the center of the partition-plate 23, which constitutes the bottom of the water-recep.--

tacle 24 and is provided with a discharge nozzle' 29, 'whibh terminates directly over the box or receptacle 16, and placed inthe pipe 28,

outside of the casing 22, is a valve 30, with ofwliich is weighted, as shown at 32, and the inner end of which is provided with a curved arm'33, which is adaptedto be operated by a rod 34, which is securedto the top of the drum, 6 and which is providedwith an arm 35.

"Extending from at or near the top of the receptacle 13, within the cylindrical casing ll of the generator, is a .pipe 36, which ex- ,4 through the bottom 12 of the cylindrical casing 11 and out'thro'ugh the side -thereof, as shown at 37, and this pipe 36 connects with tends through 'the' annular chamber 14 and water-in the receiver 5, and'when the drum a condenser 38 of any preferred form, which is provided atone side with-a pipe 39, through which the water" of condensation and, other material may be drawn off, and this pipe'39 is provided with a valve 40, and a pipe 4 l,is

. connected with the end of the condenser 38 opposite-that with which the pipe 36 cbmmunicates, and the pipe 41 passes into the bottom'ofthelgasometer and connects with an upright pipe 42, placed therein in the usual manner, said pipe 42 being shown in dotted lines in Fig. 1, and the pipe 41 is provided with avalve 43.

The pipe .42 constitutes the supply-pipe of thegasometer, and I also provide a dischargepipe44, which is also shown in dotted lines in Fig. 1, and with the lower end of which is 7 connected a 'pipe 45, which extends through the bottom .of the gasometer and in which is placed a valve 46, the pipe 45 being intended as a supply-pipe by means of which the gas is conveyed from the gas'ometer to the mains or pipes for use.

- The boxes or receptacles 16, 17, 18, and 19 are supported one above the other in the geii enter in any desired manner, and the tubular receptacle 15 is removable, and whenever,-

it is desired to charge the generator the upper portion, which consists of the-casing 22, is removed, and thetubular receptacle 15 isalso removed, and the boxes or receptacles 16,17,

'18, and 19 are separated and filled or partially filled with calcic carbid, and whenever it is desired to operate the apparatus the casing22,

containing the water-receptacle 24,-is placed in position and said receptacle isfilled onpa'r" tially filled with water. 'The valve 43 in the pipe 41 is. then opened and the water flows through the pipe. 28 into the upper box or receptacle'16, and this flow'may be regulated,

by the no'zzle29' as may be desired. The gas is generated by the water coming in contact with the calcic carbid in said boxor receptacle 16 and passes through the tube 36 into the gasometer, and the water will. con- .tinue to flow through the pipe" 8 until the drums of the gasometer rises, so as to operate the lever 3l.and out of! the flow of the water, and when said drum sinks to a predetermined position said lever will be operated, the valve 30 will be ope'ned, ;and the flow of water will be recom menced. .By the time the box or receptacle 16 is filled with water the calcic carbid thereinivill have lost its strength or be exhaustedand' the water will flow out through the perforations 20 in the top thereof or over the top thereof and down into the box or receptacle 17, and this operation will too be continueduntil'the .entirecliarge oft-he calcic carbid is exhausted. V y v As'long as there is calcic carbid in the gen- 'erator the production of gas will be uniform and the topof the'drum 6 will not fall more than about six, inches above the level of v the falls more thainthis amount it is a very evident si-gnthat thecalcic carbid is exhausted; In order torecharge-the generator, the le- IIO vex- 31 is turned so that it. will stand vertical and be free from the spring 35' of the d 34,

operation cuts ofl thefiow ot-thewater. The valve 43 is then closed and the valve 40 opened in order that the air may pass, so as to which is connected with the drum '6, an this fill'the vacuum which is caused bylifting orremoving the 6asing22. Said casing 22 is then lifted or removed and the generator is again recharged-,as'hereinbefore described, after which the separate parts of the generator are again connected, and the apparatus is ready for operation, the valves 39, 43, and46 being manipulated, as will be readily understood.

My improved apparatus is simple in construction and operation, and it. will be apparent that the apparatus may be made of any desired capacity, the capacity of "said apparatus depending entirely onthe size of the generator. t

It .will be apparent that many changes in and modifications of the construction herein described maybe made without departing from the spirit of my invention or sacrificing its advantages, and my invention is not therefore limited to the construction, combination, and arrangement of the separate parts v ing the water. being operated by the verti- -cally-movable drum of the gasometer, sub
